grandma's fuck cheese  

When a young adult has sex, usually in porno's, with a mature woman (60+) and licks her vagina that hasn't been shaved nor cleaned. This creates a foaming substance, almost like cheese, where the young man takes it and shoves it into her anus, where the cheese like substance is used as a lubricant.

"Yo dude, Jack played with that grandma's fuck cheese last night. Eck!!"
